Psalm 7 is bookended by two amazing verses. “O LORD my God, in you do I take refuge,” is the first half of verse one. Then, David closes with “I will give to the LORD the thanks due to his righteousness, and I will sing praise to the name of the LORD, the Most High.”
In between, we have a picture of God as judge and the judgments he makes. In verses 3-5, David calls down judgment on himself if he is in the wrong. Verses 6-11 contain phrases like, “you have appointed a judgment,” (v.6); “The LORD judges the peoples; judge me, O LORD, according to you my righteousness,” (v.8); “you who test the minds and hearts,” (v.9); and, “God is a righteous judge,” (v.11). Verses 12-16 seem to be a description of God’s judgment.
So, I think it’s fair to say we’ll be talking about judgment over the course of the next few posts.
In the heading, we’re given this little tidbit: “A Shiggaion of David, which he sang to the Lord concerning the words of Cush, a Benjaminite.”
So, who was Cush? To be honest, I’ve got nothing. Cush is not mentioned specifically anywhere in Scripture in this type of context. The study note on the heading from the Lutheran Study Bible says, “Since Cush was from the tribe of Benjamin, he was almost certainly an ally of David’s enemy Saul.” That might even be stretching things a bit too far.
There are no direct citations of Psalm 7 in the New Testament that help give us anymore context.
First, this will be the longest Psalm that we’ve studied. It’s still looking like, at least for now, that we’ll do the study in five sections (1-2, 3-5, 6-11, 12-16, 17).
There appears to be a good mix of Law/Gospel and justification language in the Psalm. There are a couple mentions of “righteousness” and a mention of repentance for us to work with.
In verses 3-5, we’ll be afforded a real golden opportunity for self-examination. It will be a time for asking some honest questions and hopefully giving some honest answers.
Finally, I am really looking forward to studying verse 14. I love the pattern it gives: “Behold, the wicked man conceives evil and is pregnant with mischief and gives birth to lies.” There’s definitely progression in that verse.

 I’m not sure we can say anything with certainty when we’re not given the context.
